Extended Data Fig. 7: Characterization of MLN and splenic bacterial taxa at family level in preweaning mice with and without L. animalisWU feeding.

Cellular populations from the a) MLN and b) spleen were isolated and treated with propidium monoazide and photoactivation, DNA was isolated and bacterial taxa were characterized by 16 s rRNA v4 sequencing. The number of different taxa identified were not dramatically altered by L. animalisWU feeding.
